What is your substance, whereof are you made,
That millions of strange shadows on you tend?
Since everyone hath, every one, one shade,
And you, but one, can every shadow lend.
Describe Adonis, and the counterfeit
Is poorly imitated after you;
On Helen's cheek all art of beauty set,
And you in Grecian tires are painted new.
Speak of the spring, and foison of the year;
The one doth shadow of your beauty show,
The other as your bounty doth appear,
And you in every blessèd shape we know.
In all external grace you have some part,

So am I as the rich whose blessèd key
Can bring him to his sweet up-lockèd treasure,
The which he will not every hour survey,
For blunting the fine point of seldom pleasure.
Therefore are feasts so solemn and so rare,
Since, seldom coming, in that long year set,
Like stones of worth they thinly placèd are,
Or captain jewels in the carcanet.
So is the time that keeps you as my chest,
Or as the wardrobe which the robe doth hide,
To make some special instant special-blest
By new unfolding his imprisoned pride.

Thus can my love excuse the slow offence
Of my dull bearer, when from thee I speed:
From where thou art, why should I haste me thence?
Till I return, of posting is no need.
O, what excuse will my poor beast then find
When swift extremity can seem but slow?
Then should I spur, though mounted on the wind;
In wingèd speed no motion shall I know.
Then can no horse with my desire keep pace;
Therefore desire, of perfect'st love being made,
Shall neigh, no dull flesh in his fiery race;
But love, for love, thus shall excuse my jade:

How heavy do I journey on the way,
When what I seek, my weary travel's end,
Doth teach that case and that repose to say,
"Thus far the miles are measured from thy friend!"
The beast that bears me, tired with my woe,
Plods dully on, to bear that weight in me,
As if by some instinct the wretch did know
His rider loved not speed being made from thee.
The bloody spur cannot provoke him on
That sometimes anger thrusts into his hide,
Which heavily he answers with a groan,
More sharp to me than spurring to his side;

Those hours, that with gentle work did frame
The lovely gaze where every eye doth dwell,
Will play the tyrants to the very same
And that unfair which fairly doth excel;
For never-resting Time leads summer on
To hideous winter and confounds him there,
Sap checked with frost and lusty leaves quite gone,
Beauty o'ersnowed and bareness everywhere.
Then, were not summer's distillation left
A liquid prisoner pent in walls of glass,
Beauty's effect with beauty were bereft,
Nor it nor no remembrance what it was.

Against that time, if ever that time come,
When I shall see thee frown on my defects,
When as thy love hath cast his utmost sum,
Called to that audit by advised respects;
Against that time when thou shalt strangely pass,
And scarcely greet me with that sun, thine eye,
When love, converted from the thing it was,
Shall reasons find of settled gravity—
Against that time do I ensconce me here
Within the knowledge of mine own desart,
And this my hand, against myself uprear,
To guard the lawful reasons on thy part.

How careful was I, when I took my way,
Each trifle under truest bars to thrust,
That to my use it might unusèd stay
From hands of falsehood, in sure wards of trust!
But thou, to whom my jewels trifles are,
Most worthy comfort, now my greatest grief,
Thou best of dearest, and mine only care,
Art left the prey of every vulgar thief.
Thee have I not locked up in any chest,
Save where thou art not—though I feel thou art—
Within the gentle closure of my breast,
From whence at pleasure thou mayst come and part;

Betwixt mine eye and heart a league is took,
And each doth good turns now unto the other,
When that mine eye is famished for a look,
Or heart in love with sighs himself doth smother,
With my love's picture then my eye doth feast
And to the painted banquet bids my heart;
Another time mine eye is my heart's guest,
And in his thoughts of love doth share a part.
So, either by thy picture or my love,
Thyself, away, art present still with me;
For thou not farther than my thoughts canst move,
And I am still with them, and they with thee;

Mine eye and heart are at a mortal war
How to divide the conquest of thy sight;
Mine eye my heart thy picture's sight would bar,
My heart mine eye the freedom of that right,
My heart doth plead that thou in him dost lie—
A closet never pierced with crystal eyes—
But the defendant doth that plea deny,
And says in him thy fair appearance lies.
To 'cide this title is impanellèd
A quest of thoughts, all tenants to the heart,
And by their verdict is determinèd
The clear eye's moiety, and the dear heart's part.

The other two, slight air and purging fire,
Are both with thee, wherever I abide;
The first my thought, the other my desire,
These present-absent with swift motion slide.
For when these quicker elements are gone
In tender embassy of love to thee,
My life, being made of four, with two alone
Sinks down to death, oppressed with melancholy;
Until life's composition be recured
By those swift messengers returned from thee,
Who even but now come back again, assured
Of thy fair health, recounting it to me.
